1.1 该分类涵盖了商业上称为再生硫化颗粒橡胶的复合材料。再生硫化橡胶颗粒是指通过某种方式处理硫化橡胶以获得所需粒径分布时产生的产品。 1.2 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 再生硫化橡胶颗粒在橡胶配合中很重要。它允许橡胶复合物将一定百分比的橡胶填料添加回其母体或类似化合物中，或将该材料用作替代物或独立化合物。其使用可能降低化合物成本或改善性能特性，或两者兼而有之。 4.2 许多类型的再生硫化橡胶颗粒可用，硫化橡胶颗粒的类型数量仅受母体化合物数量的限制。 4.3 再生硫化颗粒橡胶用作热分解、脱硫、回收炭黑、轮胎衍生骨料、合成草皮填充物、沥青橡胶、模制橡胶制品、轮胎的原料- 衍生燃料，以及其他轮胎和非轮胎衍生产品和最终用途。 4.4 使用再生橡胶对环境有积极影响。

1.1 This classification covers the compounding material commercially known as recycled vulcanizate particulate rubber. Recycled vulcanizate particulate rubber is the product that results when vulcanizate rubber has been processed by some means to obtain a desired particle size distribution. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 Recycled vulcanizate particulate rubber is important in rubber compounding. It allows the rubber compounder to add a certain percentage of rubber filler back into its parent or similar compounds or to use the material as substitute or stand alone compound. Its use may lower compound costs or improve performance characteristics, or both. 4.2 Many types of recycled vulcanizate particulate rubber are available, with the number of types of vulcanizate particulate rubber limited only by the number of parent compounds. 4.3 Recycled vulcanizate particulate rubber is used as feedstock for thermal decomposition, devulcanization, recovered carbon black, tire-derived aggregate, synthetic turf infill, asphalt-rubber, molded rubber products, tire-derived fuel, and other tire and non-tire derived products and end uses. 4.4 Use of recycled rubber has a positive environmental impact.
